Description
Technical Field
The invention relates to the technical field of dry ironing equipment, in particular to a temperature control method and device of dry ironing equipment.
Background
In general, a drying and ironing machine sucks water from laundry by using hot steam generated by a heating system such as a heat pump, so as to dry the laundry, and irons the laundry during drying to flatten the laundry. The ironing head of a common dry ironing machine is composed of structures such as an electric heating wire, a metal bottom plate and a metal sheet. The heating pump system heats the heating wire, hot steam generated after moisture is heated and evaporated by the heating wire is transmitted out through the metal bottom plate, and the metal bottom plate is close to the surface of clothes during use, so that the clothes can be dried and ironed. Therefore, when the dry ironing machine is used, the ironing surface, namely the metal bottom plate, needs to be heated to a certain temperature before the dry ironing machine can be used.
The existing dry ironing machine directly heats according to the set required temperature when in use, and stops heating when detecting that the ironing surface reaches the set temperature. However, in order to ensure that the whole surface of the ironing surface can completely reach the set required temperature in use, a user may wait for a period of time after heating to reach the set temperature, so that the whole surface of the ironing surface reaches the required temperature through sufficient heat conduction and then starts to be used. The heating bodies used by each type of dry ironing machine are different, and meanwhile, under the set temperatures of different requirements, the heat generated by each type of heating body is different, so that the time required by heating is different, and then after the heating is completed, the heat generated by the heating body is different, so that the heat conduction speed is different, so that the time for uniformly covering the whole ironing surface by heat conduction is different, and the waiting time required by uniform temperature rise is currently completely unknown.
The time required for the machine to be left for a period of time after heating has been completed to allow the entire ironing surface to reach the set temperature uniformly is also completely uncertain for most users. The length of the time for waiting the dry ironing machine is generated according to personal experience of a user or theoretical derivation, if the experience of the user is rich, the time required to wait may be completely clamped during derivation, so that the heating effect is optimal, but for most users, the definite waiting time cannot be completely realized, so that the waiting time is not too long, the dry ironing machine is always in a heating state for too long, and unnecessary resource waste is caused.
Therefore, it is necessary to provide a temperature control method and device for a dry ironing device to solve the problem that the temperature rise time of the dry ironing machine cannot be controlled during use, and unnecessary resource waste is easily caused.
Disclosure of Invention
The invention aims to provide a temperature control method and a temperature control device for dry ironing equipment, and solves the problem that the temperature rise state cannot be controlled when a dry ironing machine is used, and resource waste is easily caused.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention is used for regulating and controlling the temperature rise process of a heating body in the use of a dry ironing machine, so that the temperature rise time is accurate and controllable, and the resource waste is avoided, and particularly relates to a temperature control method of dry ironing equipment, which specifically comprises the following steps:
s1, setting a heating temperature T required by dry ironing of dry ironing equipment;
s2, detecting the actual temperature T of the heating body in the current dry ironing equipment t ；
S3, obtaining the actual temperature T t Comparing with the set heating temperature T to obtain the temperature difference T of the current heating body 1 ；
S4, according to the set judgment standard, the currently obtained temperature difference T is measured 1 Judging, and regulating and controlling the current input power of the heating body according to a preset regulation and control mode according to a judgment result to obtain a regulation and control power P;
s5, adjusting the obtained regulation power P according to a set adjustment mode to obtain the adjusted control power P 0 And let the heating body follow the control power P 0 And when the temperature of the heating body reaches the set heating temperature T, stopping power input to the heating body within a set time period.
The principle and the advantages of the scheme are as follows:
according to the scheme, on the basis of monitoring the temperature information, the temperature rise process is regulated and controlled by controlling the output power, so that the phenomenon that the temperature is controlled inaccurately due to the feedback of single temperature information is avoided. In addition, the output power is controlled to regulate the heating process, so that the control is not limited by temperature feedback, the control is more comprehensive and stable, the controllability of the heating process is effectively ensured, the heating time is accurately controlled, and the resource waste is avoided.
It is worth to be noted that, the existing dry ironing machine only needs to directly heat the temperature of the ironing surface to the set temperature, and the current temperature of the ironing surface is monitored as temperature information to feed back when the set temperature is judged to be reached, so as to control the heating time. The temperature information of a certain point on the ironing surface is generally monitored and controlled as feedback information when the temperature of the existing dry ironing machine is monitored, but for the whole ironing surface, the heat conduction needs time, the monitored certain point can not ensure that the temperatures of all the surfaces reach the set temperature at the same time, and because the generally adopted detection parts are all electronic elements, the whole ironing surface can not be covered when the detection points are arranged, and information delay or error can be formed due to heat conduction when the temperature is monitored and fed back.
For a user, the operation habit of waiting for a period of time after the heating of the dry ironing machine is finished is already common, and the waiting time can be omitted or clearly controlled after being completely ignored; at present, the process of fully heating the dry ironing machine after heating does not have a definite technical means to achieve an accurate control effect, so that a user is completely unknown in waiting time, uncertain waiting time can be generated, the waiting time is excessive or unnecessary under most conditions, resource waste is caused to a certain extent, the time of the user can be consumed, the dry ironing machine can be damaged in the long-time unnecessary waiting heating process, the service life of the dry ironing machine is shortened, and meanwhile, danger can be brought if heat is gathered too much. Therefore, the method overcomes the technical prejudice that the waiting time after the temperature of the dry ironing machine is raised is very necessary to control so as to definitely reach the time for comprehensively covering the ironing surface by the temperature after the set temperature is reached, thereby reducing the resource waste, improving the use effect, prolonging the service life of the dry ironing machine and increasing the use safety.
Meanwhile, in the current temperature monitoring of the dry ironing machine, the temperature is generally controlled and regulated from the most intuitive heating effect, namely, a regulation and control mode of temperature control feedback is adopted to regulate and control intuitively and quickly, but the control mode is easy to cause monitoring delay or error because of the single occurrence of a monitoring point. And this application has overcome above-mentioned technical bias, and input power and then control the intensification process through the control heating member can accurately infer heat conduction time, promotes the control precision to avoid the monitoring condition of error to appear, effectively accurately regulate and control the intensification process.

Temperature difference T to be obtained 1 And a standard threshold value T 0 The comparison is carried out, and then the difference range of the current temperature difference is rapidly judged, so that the corresponding control mode is conveniently and rapidly carried out, and the heating control efficiency is higher. Meanwhile, according to the temperature difference and the standard threshold value T 0 The comparison result can adopt a flexible control mode, thereby achieving the effect of accurate regulation and control, shortening the regulation and control time and ensuring that the regulation and control process is completed accurately and efficiently. And when the temperature difference T is 1 Greater than a standard threshold T 0 When the temperature is higher than the set heating temperature, the output power can be turned on completely, so that the temperature is increased quickly, the temperature rise process is accelerated, and power consumption is avoided after long-time waiting. When the temperature difference T is 1 Less than a standard threshold T 0 When the temperature is higher than the set temperature, the heating temperature is higher if the output power is turned on, which leads to excessive heating temperature, waste of excessive heat and easy scald; the excess power that is simultaneously output is also a waste.

The input power is divided into a plurality of parts, each part is independently regulated and controlled, the input power is refined and controlled, and the regulation and control accuracy and stability are ensured. Meanwhile, the regulation and control are carried out by combining the comparison result, the regulation and control mode is more flexible, the regulation and control efficiency is higher, the regulation and control effect can be more quickly and accurately achieved, unnecessary resource waste is avoided, and the effects of energy conservation and consumption reduction are achieved.
Preferably, as a modification, the division strategy is to divide the input power of the heating body per unit time into N parts.

And after multi-factor comprehensive regulation and control, the final output power is formed by superposing three modes, so that the regulation and control accuracy and stability are ensured, and the generated error is reduced.
Preferably, as an improvement, in S4.2.2, the temperature rise speed of the current heating body is determined according to the difference between the current temperature of the heating body and the previous second temperature, and the larger the difference is, the faster the temperature rise speed is.

Times.e (e (n-x))); wherein e is the current temperature of the heating body; e (n-1) is the temperature of the heating body one second before; e (n-X) is the temperature of the heating body X seconds ago.

Detailed Description
The following is further detailed by way of specific embodiments:
example one
Substantially as shown in figure 1: a temperature control method of a dry ironing device is used for accurately regulating and controlling the temperature rising process of a dry ironing machine, effectively improves the regulation and control efficiency, and avoids causing unnecessary resource waste. The method specifically comprises the following steps:
step one, setting a heating temperature T required by dry ironing of dry ironing equipment;
step two, detecting the actual temperature T of the heating body in the dry ironing machine through a temperature sensor t ；
Step three, obtaining the actual temperature T t Comparing with the set heating temperature T to obtain the current temperature difference T 1 Wherein the temperature difference T 1 Is defined as T 1 ＝T-T t (ii) a Simultaneously, the temperature difference T is determined according to the determination standard 1 And a set standard threshold value T 0 Comparing, in this embodiment, the standard threshold T 0 The setting range is 40-50 ℃; the judgment criterion is the current temperature difference T 1 Greater than a standard threshold T 0 Then, the regulated power P is the current output power; when temperature difference T 1 Less than a standard threshold T 0 And then, regulating and controlling the current output power according to a preset regulation and control mode to obtain regulated and controlled regulation and control power P.
Step four, when the temperature difference T 1 Less than a standard threshold T 0 And then, regulating and controlling the current output power according to a preset regulation and control mode to obtain regulated and controlled regulation and control power P. The regulation and control method comprises dividing the input power of the heating body in a specified unit time into N parts to obtain N parts of unit power P n (ii) a Then the unit power P is divided from N parts according to the set regulation strategy n Respectively select and output the first power P a A second power P b And a third power P c The regulated power P is a first power P a A second power P b And a third power P c Sum, defining the expression of regulated power P as P = P a +P b +P c . In this example, the predetermined unit time was set to 1 second, the input power of the heating element in 1 second was equally divided into 50 parts, and the standard threshold T was set 0 The value of (A) is 50 ℃. I.e. when the temperature difference T 1 Greater than a standard threshold T 0 When is at timeWhen T is 1 When the temperature is higher than 50 ℃, the difference between the current temperature Tt and the set heating temperature T is larger, and the output power is full power at the moment, so that the heating body is in a full output state to quickly raise the temperature. When the temperature difference T 1 Less than a standard threshold T 0 When is at T 1 When the temperature is lower than 50 ℃, 50 parts of unit power P is subjected to the set regulation strategy n And performing regulation control to control the heating output state of the heating body.
Specifically, when T is 1 When the temperature is less than 50 ℃, the adjusting strategy comprises the following three judgment modes:
first, according to the currently obtained temperature difference T 1 From N parts of unit power P n In the selection of A parts of unit power P n As a first power P a Where A < N, at a first power P a According to the temperature difference T 1 To determine the output fraction a, i.e. the first power P a Is expressed as P a ＝T 1 ＝T-T t ；
Secondly, judging the speed of the heating speed of the current heating body, and performing N parts of unit power P according to the speed of the heating speed n In the selection of B parts of unit power P n As a second power P b Wherein B is less than N. At the moment, whether the current temperature rising rate is too fast or too slow is judged by combining the temperature rising speed, so that the second power P is determined b Output number of copies B. The heating speed of the heating body is specifically the difference value between the current temperature and the last second temperature of the heating body detected by the temperature detector, and the expression of the heating speed is defined as E = T t -T (t-1) At a defined second power P b Expression of function P b = KI (e + (e (n-1)) + (e (n-2)) + (e (n-3)). Eta (e (n-x))), wherein e is the current temperature of the heating body; e (n-1) is the temperature of the heating body one second before; by analogy, e (n-X) is the temperature of the heating body before X seconds, and finally the second power P is obtained b A value of (d);
finally, according to the difference value of the heating quantity and the heat dissipation quantity of the heating body in the set time in the current environment, the unit power P is divided by N n In the selection of C parts of unit power P n As a third power P c WhereinC is less than N. In this embodiment, the setting time is set to 1 second, the heating capacity and the heat dissipation capacity in the current environment are monitored within 1 second, a difference is obtained by measurement and calculation, and an algorithm expression P is defined c = (e-Last _ e), wherein e is defined as the current temperature of the heating body; last _ e is the temperature of the heating body for one second, and the third power P is obtained c Therefore, the balance relation between the heating quantity and the heat dissipation quantity within 1 second is broken through, and the heating effect is ensured.
Obtaining a first power P according to the regulation result a A second power P b And a third power P c Adding to obtain a regulated power P, wherein an expression of the regulated power P is defined as:
P＝P a +P b +P c ＝(T-T t )+(KI(e+(e(n-1))+(e(n-2))+(e(n-3))......e(e(n-x))))+(e-Last_e)。
step five, adjusting the obtained regulation power P according to a set regulation mode to obtain the regulated control power P 0 Inputting control power P to the heating body 0 And when the temperature of the heating body reaches the set heating temperature T, stopping power input to the heating body within a set time period. And the adjusting mode is to adjust the obtained regulating power P to be within a set numerical range. In this embodiment, the set waiting time period is 5 seconds, and the value range for adjusting the regulated power P is set to be 0 to 50. After the regulated power P is obtained, the regulated power P is automatically adjusted according to the output state of the heating body and a set numerical range, namely when the obtained regulated power P is less than 0, the regulated power P is adjusted to 0 to serve as the control power P 0 Outputting; when the obtained regulated power P is more than 50, the regulated power P is adjusted to 50 as the control power P 0 And (6) outputting. When the heating body reaches the set heating temperature T, the heating body stops working after 5 seconds, so that the temperature of the ironing surface is ensured to meet the requirement; and thereby ensure control power P 0 The effectiveness and stability of the device can avoid damage to the dry ironing machine, and avoid the conditions of abnormal control power and the like, influence on use and even cause danger.
Meanwhile, the invention also provides a temperature control device of the dry ironing equipment, which is applied to the control method, so that the temperature rise process of the dry ironing machine can be accurately regulated and controlled, and the energy waste is avoided.
In the embodiment, the temperature rising process of the dry ironing machine is controlled by adjusting the input power, so that the temperature rising is fast and controllable, the waiting time is effectively reduced, and the energy-saving effect is achieved. Meanwhile, the input power is uniformly divided into 50 parts for regulation and control, and the 50 parts of input power are respectively regulated and controlled comprehensively according to factors such as temperature difference, heating speed of the heating body, heat dissipation capacity in the current environment and the like, so that the control precision is improved, and the regulation error is reduced. And delay caused by temperature detection alone can be effectively avoided by controlling the output power, timely and quick adjustment is realized, the calculation amount is small, and meanwhile, the accuracy is improved.
Simultaneously, this application comes the intensification process of control temperature through input power, compares in the control mode of simple dependence temperature feedback, and this application effectively avoids the inhomogeneous condition of temperature detection to can reduce the error that detects and bring, and can accurately regulate and control the control power of heating member through input power, and then clearly control the heat of heating member, consequently can fundamentally control intensification process, accomplish effective, accurate, timely regulation and control, and with the so-called "latency" of user's clarity, and then reach the regulation and control effect of energy-conservation and loss-reduction.
Example two
Different from the first embodiment, the present embodiment further includes setting the type of the clothes to be ironed, and adjusting the heating temperature according to the set type, so as to ensure that the clothes will not be scalded at the final temperature. Meanwhile, the control power is automatically adjusted according to the adjusted heating temperature, so that the dry ironing temperature is the optimal dry ironing temperature of the clothes, if the cotton and linen clothes are dried and ironed, the cotton and linen clothes deform and shrink due to overhigh temperature, but the cotton and linen clothes are easily wrinkled and can be ironed smoothly at a certain temperature, and therefore the heating temperature cannot be overhigh or overlow and can be on the middle level by combining the judgment of the clothes. When the silk clothes are dried and ironed, the silk clothes are easy to damage and the silk clothes are not easy to wrinkle, so that the heating temperature can be lower when the silk clothes are dried and ironed, and the heating temperature can be lower under the medium condition. Therefore, after the heating temperature is regulated and controlled by combining the type of each type of clothes, the clothes can be prevented from being damaged or the dry ironing effect can not be achieved, and further the power output quantity can be effectively and reasonably planned to achieve the optimal power output.
In the embodiment, the heating temperature is adjusted according to the type of the clothes to be ironed, so that the input power is controlled, the input power is effectively adjusted and controlled on the basis of the type of the clothes, the output power is fully utilized, the heat conduction effect of the heating body is optimal, the use effectiveness and convenience of the dry ironing machine are improved, the optimal ironing effect is ensured, and the clothes can be protected; meanwhile, the input power can be balanced and adjusted in real time by combining the heating temperature required by the current clothes, so that waste caused by too much power is avoided, or the ironing effect is too little to be achieved, and further the waste of resources is also caused.
EXAMPLE III
Different from the first embodiment, the present embodiment further includes identifying and determining the humidity and the temperature of the current ambient environment, and the determination may be specifically implemented by using a sensor, for example, in the high-temperature but high-humidity environment of Chongqing, if the determination is performed only by using the ambient temperature, the temperature required for dry ironing may be correspondingly reduced by determining the external high temperature, and it is considered that the difference between the heat dissipation amount and the heat addition amount breaks through the balance, so as to reduce the output power. However, because the outside humidity is very high, the temperature regulated and reduced cannot achieve the dry ironing effect, and even if the dry ironing time is longer, the drying and ironing time is only wasted. Therefore, after the judgment of the ambient environment humidity is combined, the heating temperature is adjusted according to the humidity, the input power is controlled, the effective dry ironing effect is guaranteed, and the resource waste is avoided.
In this embodiment, adjust required temperature according to the ambient environment humidity condition when ironing, and then control input power, effectively regulate and control input power, ensure the effective dry boiling hot effect of clothing to this guarantees the best effect of ironing, also further guarantees the effective utilization of the energy, reduces energy consumption, and then the energy saving uses.
The foregoing is merely an example of the present invention and common general knowledge in the art of designing and/or characterizing particular aspects and/or features is not described in any greater detail herein. It should be noted that, for those skilled in the art, without departing from the technical solution of the present invention, several variations and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
